It isn’t really.
If you’re going to lend at 1.95% into a market where it’s nigh on impossible to enforce security, it’s logical to try and manage other risks such as the size and liquidity of the relevant housing market.
People from the back of beyond never seem to want to accept this, but houses outside of the main urban centres just aren’t as desirable from a lending perspective; typically harder to value and typically harder to sell.
That answer though is one size fits all because there are areas outside of Dublin and the main cities which are pockets of houses which are easy to value because they always maintain their value and are easy to sell (Long-standing sought after/desirable areas). That policy completely ignores this fact and just takes the easy option but by doing so they are losing out on some very reliable customers
